IMPROVEMENT IN GRAIN-SEPARATOR.

TO ALL WI-IOM IT MY CONCERN:

Be it known that I, DANIEL S. YEAKEL, of Dillingersville, in the county of Lehigh, and State of Pennsylvania, have invented a new and improved Grain-Separator for `thrcshing-nuaehines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates te a new and improved separator, for separating the grain from straw as said substances are discharged from the threshing-cylinder of a threshing-machine, whereby the work above mentioned is performed in a perfect manner. V

In the accompanying sheet of drawings-.f l

Figure l is a longitudinal verticalscction of my invention taken in the line :i: z, fig. 2. i

Figure 2,-a transversoartical section of the same, taken in the line y y,

Similar letters of reference indicate corresponding parts.

A representen framing, which may be constructed in any proper manner, so'as'to be strong and durable.

On the top of this framing there are secured two side pieces, I3 B, and between said pieces the screen C is placed, and allowed to work or swing freely.

This screen may be constructed of wood, having holes a bored through-it, of suicient diameter to admit of'the grain passing through, and to the upper surface of the screen there are attached two longitudinal bars,

D D, which are notched at their upper edges, toiform a series of projections, b, as shown clearly in iig. l.

The screen has two transverse bars, e c, secured to its under side, said bars having tenons formed at their ends to pass loosely through the lower ends of bars E, the upper endsof the latter being fitted loosely on the ends of transversehars F F,which are permanently secured to the upper edges of theside pieces 'B B.

To each side of the screen C there is attached a strip, d, which extends up a short distance above the upper surface of the screen, and serves to prevent grain from passing down between the screen and side pieces.

To the lsupports e e, at the discharge-end ot' theframing A, there is attached-a horizontal spring, DX, and to the lower cross`piece,f, of these supports, there is attached the lower end of a vertical spring, EX, which -spring is attached to the spring D, by a bolt,iF and nut,g, the bolt being allowed to work a little in spring DX.

The upper end of the spring,r EX is connected hy a'rod, It, with the bottom of' the screen Opas shown at z'.

The discharge-end of the framing and screen are slightly elevated, and-a swinging, reciprocating motion is lgiven the screen, in any proper manner, from-the 'working parts of the threshing-machine. v

The grain and straw are discharged upon the rear and depressed or vlower part of the screen, the straw being ff gradually shoved forward, and discharged from the elevated en d of the screen, in consequence of the projections Zz acting against it, the grain, under the'motion of the screen, passing through the pcrforations thereof,

he springs cause the screen to operate with a uniform motion, which is well calculated to separate the loose grain from the strax. as the latter is moved along over the surface of the screen, and the screen, owing to the way in which it ishung, has an upward and downward swinging movement, which greatly favors the end above mentioned.

I claim as new, and desire tosecure b y'Lettcrs'Iatent- The swinging screen C, hung or suspended as shown, in combination with the springs D EX, all arranged and applied in the manner substantially as and for the purpose set forth.
